16 Facts About Neon


Neon is a chemical element with the symbol Ne and atomic number 10.

FactSnippet No. 737,351

Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.

FactSnippet No. 737,352

Neon was the second of these three rare gases to be discovered and was immediately recognized as a new element from its bright red emission spectrum.

FactSnippet No. 737,353

Neon is chemically inert, and no uncharged neon compounds are known.

FactSnippet No. 737,354

Neon is used in some plasma tube and refrigerant applications but has few other commercial uses.

FactSnippet No. 737,355

Neon was discovered in 1898 by the British chemists Sir William Ramsay and Morris Travers in London.

FactSnippet No. 737,356

Neon was discovered when Ramsay chilled a sample of air until it became a liquid, then warmed the liquid and captured the gases as they boiled off.

FactSnippet No. 737,357

Neon's scarcity precluded its prompt application for lighting along the lines of Moore tubes, which used nitrogen and which were commercialized in the early 1900s.

FactSnippet No. 737,358

Neon tubes were introduced to the U S in 1923 with two large neon signs bought by a Los Angeles Packard car dealership.

FactSnippet No. 737,359

Neon content observed in samples of volcanic gases and diamonds is enriched in Ne, suggesting a primordial, possibly solar origin.

FactSnippet No. 737,360

Neon plasma has the most intense light discharge at normal voltages and currents of all the noble gases.

FactSnippet No. 737,361

Neon is abundant on a universal scale; it is the fifth most abundant chemical element in the universe by mass, after hydrogen, helium, oxygen, and carbon .

FactSnippet No. 737,362

Neon is monatomic, making it lighter than the molecules of diatomic nitrogen and oxygen which form the bulk of Earth's atmosphere; a balloon filled with neon will rise in air, albeit more slowly than a helium balloon.

FactSnippet No. 737,363

Neon is the first p-block noble gas, and the first element with a true octet of electrons.

FactSnippet No. 737,364

Neon is often used in signs and produces an unmistakable bright reddish-orange light.

FactSnippet No. 737,365

Neon is used in vacuum tubes, high-voltage indicators, lightning arresters, wavemeter tubes, television tubes, and helium–neon lasers.
